2. General info

        It has become an irreversible trend for the papermaking industry to change from acid to alkaline. The most fundamental change is the shift of sizing agent from traditional rosin agent to medium-alkaline sizing agent.

        AKD is one of the most excellent sizing agents in medium-alkaline sizing agent. AKD emulsion can be used directly in paper mills for sizing in pulp. It can make paper with superior water resistance, acid resistance and alkali resistance, and greatly improve the physical properties of paper.


3. Application

        AKD wax 1840 do not contain toxic substances, such as toluene, etc. since we use solventless production process. So our product is especially suitable for the producing of liquid food packaging paper. It is easy to emulsify. C-starch or cationic polymer is usually used as emulsifier and it can be melted at 40-50℃. In the melting process, the melting temperature should be strictly controlled. When the temperature exceeds the required value, the sizing performance and stability of AKD emulsion will be affected. At the same time, the working process of valve homogenizer will directly affect the quality of AKD emulsion, so the pressure of valve homogenizer should be kept at the required stable value.


4. Packaging and storing

        Packing: 25kg OR 500kg woven bag with PE-Liner.

        Storing: This product should be stored in the drying room. Avoid light, sun and freezing. Temperature should below 30℃.
